The X-ray structure showed octahedral complexes with a fac-coordination of two tridentate<br />

ligands in contrast to the situation where only one tridentate N,P,N ligand is coordinated to<br />

the metal centre observed for ruthenium complexes with ligands 2 or NOPON Me2 . 38, 41 The<br />

doubly positive charge of the metal centre is compensated by the dianion (µ-<br />

oxo)bis[trichloroferrate(III)] (Fe2OCl6) 2- which results from the partial oxidation of the Fe(II)<br />

precursor. 52-55 The stoichiometry of three iron atoms for two ligands in complexes 10 and 11<br />
